Use the table below to answer questions 4.5 – 4.7: This tablecontains the same client data as the first table. This time,though, the instructor is interested in knowing how his clients’other activities might impact their average cycling speed in spinclass. He notes that half of his clients also ride bikes outsideduring the week, while the other half of his clients do not bikeanywhere except spin class.

4.5 Calculate SS for each sample of spin class clients (theportion who ride outside and the portion who only do spin class).Show Work by inserting numbers into the table to show intermediatesteps Rides Outside SS = Only Spin Class SS =
4.6 Calculate s for each group Rides Outside s = Only Spin Classs =
4.7 Based on the statistics you have computed, does there appearto be any difference in average speed between those who bikeoutside and those who only bike during spin class?
Explain why or why not?
